摘　　要：齐大山铁矿西帮的降水和河流入渗补给、地表水径流等,会造成地下水流动的复杂性和不确定性;因此采用Visual MODFLOW Flex数值模拟软件预测不同频预期的最大降雨量和河流入渗补给作用下的第四系边坡的渗水量值,并建立响应关系。结果表明:在丰水期河流补给呈现稳定补给状态,主要补给项为降雨直接汇入,而降雨入渗对地层的补给比重随着降雨量增大持续增长,两者的线性拟合程度较高,经过分析计算得出拟合优度R2的数值为0.998。The precipitation, river infiltration recharge and surface water runoff in the west slope of Qidashan Iron Mine will cause the complexity and uncertainty of groundwater flow. Therefore, the Visual MODFLOW Flex numerical simulation software is used to predict the maximum rainfall expected at different frequencies and the seepage value of quaternary slope under the action of river infiltration recharge, and the response relationship is established. The results show that in the wet season, the river recharge presents a stable recharge state, the main recharge item is the direct inflow of rainfall, and the recharge proportion of rainfall infiltration to the stratum continues to increase with the increase of rainfall. The linear fitting degree of the two is high, and the value of goodness of fit R~2 is 0.998.
